Start with conditions, not a product
Cracks and sticking doors are clues, not diagnoses: around Fayetteville, sandy Sandhills soil along the Cape Fear River means grading, drainage, framing, and foundation type all need to be weighed together before a repair plan is proposed.

- Whether the settlement is progressive or reverses with the seasons

Fayetteville context
Sandy Sandhills soil is why foundation trouble in Fayetteville often looks different from the Piedmont clay problems described an hour up the road. Sand does not swell and shrink with moisture the way clay does, so the seasonal movement that dominates diagnosis elsewhere is less of a factor here. What sand does instead is move: it drains fast, and concentrated water traveling through or beneath it carries fine material away, which creates voids under footings and slabs and produces settlement that is localized and progressive rather than seasonal and reversible. That distinction matters, because a problem that will not correct itself on the next dry spell should be addressed rather than watched. The city's housing eras then fail in their own ways -- historic and military-era houses on piers and unreinforced walls showing sloping floors, newer subdivisions raising questions about fill and compaction instead.
